Baling with Hst?

[Branchchipper]

A old debate has resurfaced locally. I remember many past discussions about the inadvisability of using a hydrostatic tractor to run a pto baler.
I realized that I don't, however, have any concrete evidence that this is "bad" for the tractor.

In my neighborhood are an L5030hst, a Ford 3000 and a Ford 5000. In my book, the 5000 is the obvious baler tractor (the baler in question this time is an older mid-size JD rectangular baler of unknown PTO hp requirement)

Of the three tractors, however, the L5030hst, however, is in the best shape with regard to brakes and everything else.

So, what are the issues with this load on the Hst's pto (provided that it turned out to be an OK match with regard to pto hp)?

I don't think it's the load on the PTO. I thought if I remember right it was more of the load the baler puts on the trans. The plunger going back and forth puts stress on the trans. Or at least I know some have claimed that. I have never baled with a HST so never tried it.

Maybe by saying HST you are defining an upper limit to tractor HP that implies a tractor weight that doesn't work well with most full sized balers? Not sure if that's even remotely true...

That plunger stress load is exactly the issue, from what I've been told.

I just wanted to see if anyone had specific experience with or evidence of same.

I bale with a older small hp requirement baler. Used it with a 22hp Yanmar, too. (which I just located some old VHS video of). Its NOT a power problem, cooling maybe.

That being said, I would use the heaviest tractor available for the most comfort. The plunger loads are filtered by the inertia of the flywheel. Make sure the hitch is tight. Most complaints come as a reslt of a sloppy hitch in the fore aft direction which makes the combination of tractor, baler and wagons chuck back and forth.

On a HST, trans cooling fan and oild cooler should be checked to make sure its all there. I would say that designers know that their products will be used for this application.

Plenty of videos of an HST baling on YouTube....

HST is fantastic on a baler, the older IH's were popular. I've used my L5030HSTC for years, its baled about 30,000 bales now? I use my MF5455 sometimes now but the Kubota is still handier.

My son ground feed with the L3940 and a CaseIH 1250 Grinder/Mixer the other week because everything else was either busy or had something hooked up to it. To his surprise it pulled the big grinder like a charm. Now he didn't feed the Oats, ear Corn and pellet protein feed like he would have with the 100hp tractor but he said it did great. I shot a short video of it pulling the PTO driven grinder.

I could see that. I've seen the ol' JD 24T baler rock the IH 574 back and forth a few inches with it sitting still on flat ground in neutral without the park brake set, I'm certain it was the plunger doing it.

The problem is that the plunger strokes can cause distinct repetitive changes in the pull force. In the range for desired travel speed, these can easily be enuf to near or exceed the pressure relief rating of the hyd drive. Multiply this by 60 per minute ... for hrs.

Any PTO work is best done by hydro's because of the ability to adjust to the work. The rocking from square balers has never been a problem for hydro's although I could see where someone could use it to slander the hydro's ability.

We had a fellow who had some hay down and the ford 5000 broke and rain was coming. The only other tractor that was available was the BX 24 that was towing the wagons so that is what they baled the last two loads with!
